' TRAIN-PIPE conrLmG.

To all whom-it may concern! Be it known that I,- ERYE L; AnAMs,- a

citizenof the, United" States, residing at 'Middleton, in the county-ofCanyon, State :of Idaho, have invent'edcertain, new and usefulvImprovements in Train-Pipe Oou-, plingsf and Ido hereby declare thefollowing to be a} full, clear, and exact'description of the invention,such as" will enable-others I skilled in the art to which it appertainsto make. and use the same.

Thisinvention relates to couplers of; the kind designed to connectsections of car sup-i ported pressure. pipe,

One obj ect of the invention is to simplify the construction of devicesof'this character.

.Another object of the invention is to pro- Vida. a. novel means wherebysuch devices be-caused they are. inexact al-inement, or.not.

Athird object of the invention isto proto engage no matter whether videanovel form of out off valve for a device of this character when thesame is not engaged with another section;

the invention-consistsingeneral of atrain supported pipe coupling ofimproved charactor in combinationwith a novel means for actuatingavallv'e held in said coupler.

This coupling memberisfl-provided with a bore 21 of uniformdiameter thronghg-g out its length and by-meansof;thisconstruw tion thewalls of the coupling, member adj acent the face 19 are much thickermania;- coupling member adjacent the pipe 17' 'Attached to the eye;1,6is oneaendjof a spiral-q compression spring 22 which; surrounds thecylindrical portion of. the member 13555111 r projecting from theco'uplingfniember. c Q Upon the face of the member 1 8 -is-.an ,5elastic washer 9A providedgwith; a plurality;

do not interfere with ,i-the yielding ofth-is j washer nnder workingconditions. It will be noted-that the face 19 isr at right angles- 1.90to the axis of the, member,-l8. so ,thaf WhE II two of these memberscome together th Mouiited beneath provided with a longit'udinal t-slot-285 A 29 is indicated a butterflyvalve the stems rof p which projectlaterally through; the; sides of;

the member: 18 and which jar-e .g-squared at.

. their free ends as indicatedIatBO. Mounted:

on each of these squared-Tendsis arocke armwloo 31', the-free ends ofthis rockiar'mzbeing in spaced relation as canclearly-. bexseen iin;Fig. These rock arms,. lie2one omeach side of the bracket 27 and a--'bo1 -t .32: passes through openings 33 in the rock arms and through theslot 28.

In the operation of this device when two cars are brought together thewasher 24 of one car will strike the washer 2a of the other car and thiswill cause each of the members 18 to be forced backward until the carsare coupled when they will be maintained in this position so long as thecars remain together. When in the forward position the valve 29 liesacross the bore 21 but as the member 18 is pushed backward the endsofthe rock arms 31 will be prevented from moving backward therewith andthis will cause the valve 29 to rotate through a quarter of a circle andopen communication between the portions of the member 18 lying on eachside thereof. This backward motion is permitted by the yielding of thespring and the swinging of the triangular supporting plate 12. As soon,however, as thecars are separated the spring 22 will again force themember 18 away from the center of the car and this will close the valveby the arm 31 moving through a quarter of a circle in the reversedirection to that just described.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is
